    Do you have any updates on the three big DNA services which are more recent?
    Do you have links to any web sites which do?

    Hi Blaine, I contacted you about the year 2008 about my theory of my ancestor being the Lost King of France born in 1785 and came to America as a stow -a-way on a boat. I had my brother’s DNA test done at the time. Well now I have had his DNA tested with the R-Z381 and it has confirmed that my brother has this. They explained to me that King Louis XIIi had this mutation and that three of his proven and known descendants had this test taken and it was confirmed that this test proved that they were descended from the Royal Kings of France in the Bourbon line. Since this DNA test I had done on my brother was a mtDNA test wouldn’t it go directly back on the male line? If so, wouldn’t this be showing that my theory was correct? This Denis Beauregard says that the connection would be 4,800 years ago since it shows in the 67 test. I am not sure I understand why he is saying this. I hope you can help me with this. I know at the time you told me to find some descendants of the Kings of France to compare my brother’s DNA to. Thank you for an answer.

    I read through your Version 4 report today, great work and the sample is large enough so the results are statistically significant. I still have difficulty visualizing the relationship between the length of a single and all the possible relationships that could create that length. I took the liberty of downloading the data from the Relationship Chart Table, pages 52, 53 and plotted the data in a different format to show the relationship between match length and the biological relationships.

    I can send a copy if you are interested.
